How to create a script for update product stock. After the product stock update saves the product. Anyone helps me to create this script.


Please use this code in your phtml.

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$productId = 1; // Your Product ID
$_product = $objectManager->create('Magento\Catalog\Model\Product')->load($productId);
        'qty' => 300 //your Qty

I just tried it works. !!

Below I have write simple code for update product stock.


namespace Agtech\Productstockupdate\Block\Index;

class Index extends \Magento\Framework\View\Element\Template {

    protected $productFactory;

    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        \Magento\Catalog\Model\ProductFactory $productFactory,
        array $data = []
    ) {
        parent::__construct($context, $data);
        $this->productFactory = $productFactory;

    public function updateStock($productId,$productQty)
        $product = $this->productFactory->create()->load($productId);

                'use_config_manage_stock' => 0, //'Use config settings' checkbox
                'manage_stock' => 1, //manage product stock
                'is_in_stock' => 1, //Stock Availability
                'qty' => $productQty, //QTY


open your Phtml file and call this function $block->updateStock($productId,$productQty). like $block->updateStock(10,100) Run Cammand

  • We want this functionality using phtml file. When we run this file in front side then product stock update. – Anil Jun 17 at 12:27
  • @Anil Create block file into you module and add above code after that call updateStock function into phtml file . like $block->updateStock($productId,$productQty). I have edited code – Shorabh Jun 17 at 12:31
  • We don't clear what you say. because of we are not more familiar with coding. – Anil Jun 17 at 12:40
  • please give your phtml file path and module name. Also give block name and path if you have – Shorabh Jun 17 at 12:46
  • Module Name => Agtech/Productstockupdate Phtml file path => app/code/Agtech/Productstockupdate/view/frontend/templates/productstockupdate_index_index.phtml – Anil Jun 17 at 12:50
